[0018] A track shoe flatness automatic detection device, such as Figure 1 and Figure 2 As shown, it includes a roller conveying mechanism 9, a positioning mechanism, a supporting mechanism, a detection mechanism, a lifting mechanism and a PLC control system. The top of the supporting mechanism is fixedly connected to the positioning mechanism for positioning the workpiece to be detected. The roller conveying mechanism 9 is arranged on the side of the positioning mechanism. A lifting mechanism for adjusting the height of the detection mechanism is arranged above the positioning mechanism. The detection mechanism for detecting the workpiece to be detected is connected below the lifting mechanism. The PLC control system controls the roller conveying mechanism 9, the positioning mechanism, the supporting mechanism, the detection mechanism and the lifting mechanism to work through electrical signals. The workpiece to be detected after heat treatment is transported to the positioning mechanism through the roller conveying mechanism 9, the track plate is adjusted to be aligned with the detection mechanism through the positioning mechanism, the workpiece to be detected and the positioning mechanism are raised to a certain height by adjusting the supporting mechanism, the detection mechanism adopts the contact sensing principle to detect the surface of the workpiece to be detected, the workpiece is transported by the roller conveying mechanism 9, the position of the workpiece is adjusted by the limit mechanism, the step of transporting the workpiece during manual detection is eliminated, the labor intensity of personnel is reduced, and the roller conveying mechanism 9, the positioning mechanism, the supporting mechanism, the detection mechanism and the lifting mechanism are controlled through the PLC control system.

[0019] like Figure 4 As shown, the supporting mechanism includes a vertical linear cylinder 11 and a supporting base 10. The top end of the vertical linear cylinder 11 is fixedly connected to the supporting base 10. A positioning mechanism is arranged above the supporting base 10. The supporting base 10 is lifted by the vertical linear cylinder 11, and the workpiece to be inspected is lifted so that the workpiece to be inspected can be close to the inspection mechanism.

[0020] like Figure 3 As shown, the positioning mechanism includes a first horizontal linear cylinder 6-1 and a second horizontal linear cylinder 6-2. The first horizontal linear cylinder 6-1 is connected to a push rod 5, and the second horizontal linear cylinder 6-2 is connected to a baffle 7. The first horizontal linear cylinder 6-1 and the second horizontal linear cylinder 6-2 are symmetrically arranged on both sides of the roller conveyor mechanism 9. The first horizontal linear cylinder 6-1 drives the push rod 5 to move the workpiece to the left and fit it to the baffle 7 on the side of the roller frame. The baffle 7 can be adjusted according to the size of the workpiece by the second horizontal linear cylinder 6-2 to ensure that the plate surface area of ​​the workpiece to be inspected is exactly aligned with the inspection plate 3 in the upper lifting platform 2.

[0021] like Figure 1 As shown, the lifting mechanism includes a support frame 12, a servo electric cylinder 1 and a lifting platform 2. The servo electric cylinder 1 is fixedly connected to the top of the support frame 12, the lower end of the servo electric cylinder 1 is connected to the lifting platform 2, and the lifting platform 2 is fixedly connected to the detection mechanism. The servo electric cylinder 1 controls the lifting platform 2 to move up and down to adjust the height of the detection mechanism.

When the workpiece to be detected is transmitted to the right position, the front-end sensor 8 senses the workpiece to be detected, transmits the signal to the PLC control system, and starts the whole device. The detection plate 3 is horizontally fixed in the lifting platform 2 by bolts, and the lifting platform 2 adopts a guide column and guide sleeve structure to ensure that the sensing probe 4 follows the lifting platform 2 and moves up and down accurately in the vertical direction. Example

[0024] Based on the first embodiment, an implementation method of an automatic detection method for track shoe flatness is provided: like Figures 1 to 5 As shown, it is realized by the automatic detection device of track shoe flatness. The workpiece to be inspected after heat treatment is transported to the positioning mechanism through the roller conveyor mechanism 9, and the workpiece to be inspected is adjusted to be aligned with the inspection mechanism through the positioning mechanism; By adjusting the supporting mechanism, the workpiece to be inspected and the positioning mechanism are raised to a certain height, and the inspection mechanism uses the contact sensing principle to inspect the surface of the workpiece to be inspected; When the detection mechanism first contacts the surface of the workpiece to be detected, an induction signal is generated. The PLC control system sets the height of the top of the lifting mechanism at this time as the reference position and starts to set the descending height h again, where h is the allowable deformation of the plate surface. The lifting mechanism is lowered to a height much greater than h or much greater than the actual deformation of the workpiece. The detection mechanism portion that does not generate an induction signal can be determined to be located in the bolt hole or mud leakage hole on the plate surface. The PLC control system marks and shields the detection mechanism portion located in the hole and excludes it from subsequent statistics. The lifting mechanism is raised to the original reference position, and the remaining parts of the detection mechanism do not contact the surface of the workpiece to be detected at a given descending height h to generate an induction signal, thereby determining whether the flatness of the workpiece surface to be detected is out of tolerance.

[0025] Different from the first embodiment, the flatness of the track shoe surface is automatically detected by automatically controlling the detection mechanism, thereby improving the detection efficiency and eliminating the influence of bolt holes or mud leakage holes on the detection results, thereby improving the accuracy of the detection results.

[0026] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only used to explain the relative position relationship, movement, etc. between the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0028] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
